Which term refers to the removal of waste from the body?

• A. Absorption
• B. Distribution
• C. Sources of drugs
• D. Exertion

Answer: (D)

The concept being tested is how the body removes waste products, which is excretion. Excretion is the process by which drugs and their metabolites are eliminated from the body, helping to clear substances after absorption and distribution. It mainly happens through the kidneys (urine), but can also occur via the liver into bile and feces, the lungs (exhaled air), the skin (sweat), and even breast milk in some cases. Absorption is about taking a drug into the bloodstream, while distribution refers to moving the drug through the body to tissues; neither of these describe waste removal. Exertion is just physical effort and isn’t a pharmacology term for eliminating substances from the body.
